What HID reflectors do you use and why?
I know there are other good options, but if you only need 4" or no air-cooling, i keep coming back to the Super Sun original. I have tried Maybe 7or 8 others. The super sun original (there is a super sun 2 which i dont like as much, but it does have 6" air-cooled fittings) is extremely small and lightweight, while sending out a fairly even footprint for all size bulbs. I have used 400, 600, and 1000W in this reflector. This reflector would be good for supplemental light in a GH since it is so small it would creating little shading of natural light during the day. The only downside is it only has 4" air-cooled fittings. I ahev tried 6" and 8" air-cooled reflectors such as Cool Sun XL 8" and the Yield Master 6" and have noticed a poor light footprint (uneven) and a lot of light being lost through the holes for the ducting. The Super Sun OG has reflective covers over the air-cooled ports so that no light is lost down the air cooled ducting. I will search for an extremely in-depth post from another forum that has people taking a light meter every square inch w/ different reflectors and data logging it. If i remember correctly i think the Super Sun OG was one of the better ones (least hot spots, most even footprint). I look for that info.
I just bought 2- 6" cool tubes and i'm running 600 watts in them. They were on sale at a local hydroponics store so I thought I would try them out. I am very impressed with the light footprint. I am using them in a 8'x4' secret jardin grow tent over 3'x3' flood tables and they seem to be working well. If they weren't in the grow tent I would probably try and get a more beneficial wing, but for what I have they seem to work fine.
@jrtroubleshooter. Do you run them with an inline fan? Or is it even necessary? I see yours in the pics are really close to the plants with no air cooling, have you ever had problems?
@jrtroubleshooter. That's really good to know that you're not having problems with the lights being so close to the plants. I also thought I saw that you run 4' 8tube T5's over your clones/seedlings. Does that work well for you? I only run a single T5 over my clones and seedlings until sufficient root growth is started and it seems to work out alright.
What types of ballasts are you using for your MH and HPS cooltubes?
T5's are gr8, but they do get warm (contrary to popular belief), and they have a small light footprint once u get past seedlings, and clones. I use T5's exclusively for my seedlings and clones. I will use T5's for full grown leafy greens if i want to blast them w/ light because i keep the T5's 1-3" above the canopy. HID's on movers may be better, but i need to do actual side-by-side tests. I think im going to convert some of my laundry room to side-by-side experiments; i have always wanted to do that.
Ive got 2 400W Galaxy electronic ballast, and 1 1000W Quantum electronic ballast. What Ballast you running Logical?
Yeah I would love to see some results from that cuz I run some mature plants under 250W CFL's and they seem to love it. But overall, I don't really like CFL's. And all this talk about LED's do you guys know if they work. They are way out of my price range for what I would like to spend on lights, so I never tried them.
I run 2- 600W MH/HPS ValuLine ballasts for my cool tubes and I have a 150W Hydrofarm hood with a built in ballast. I have seen the Galaxy line and those look really nice.
AJ, How hot does your 1000W get? Do you air cool?
Did they have any algae problems in those water cooled reflectors?
That seems like a good system that you are using and I would assume you get great yields from all of that! I have never used a light rail before, how exactly do they work? I'm assuming they are automatic and move fairly slow?
Do you primarily run a flood and drain or something else?
